What should the oil pressure and normal temperature be on a T300?

I'm wondering if I may have a problem or not. The truck I drive runs at about 40 psi when I am driving. At idle, it's about 20 psi. It's not low on oil so I don't know if this is normal. Also, once the truck warms up, it runs at around 200/210. The fan will kick on if it gets any hotter and will cool it back down rather quickly. I check the coolant level each morning before starting and hardly need to add anything to it. So, is this truck starting to have problems or is this normal? It has 104 thousand miles on it

 

Kenworth T300 is a medium duty truck

 

Don't know off hand. Will be Monday before I am back at it to see

 

Well, I'm not going to worry about it. The brakes were shot on it to the point they wouldn't hold the truck on even a slight incline when the parking brake was on so I told them I didn't feel safe driving it. They got them fixed(the back ones were so bad they had to replace the entire drum on both sides) and afterwards, I was told not to drive it anymore. So, I'm having to drive a F550 pump truck now. But at least the A/C works on it..LOL
